Can dogs transmit Ebola to humans?

The Ebola diagnosis for Nina Pham is raising new questions about pets who are exposed to Ebola. Authorities in Dallas say they decided not to euthanize Pham's dog, but it is being monitored by animal control officials and the SPCA.

The dog that belonged to a Spanish nurse who contracted Ebola was not so lucky.

There are no documented cases of a dog spreading Ebola to a human. However, at least one study found dogs can get Ebola without showing symptoms. Anderson discussed this issue with former CDC disease detective Dr. Seema Yasmin and David Sanders, an Associate Professor of Biological Sciences at Purdue University.
